STEP 10. Place the brake arm in a vise (heat will make bending easier and more precise). A hammer and brute force will work in this application as well. STEP 11. After the bend is complete, install the brake arm and spin the wheel to check for clearance. If the arm clears the bolts, attach the wheel to the bike and get ready to install your motor.
STEP 12. Now that you have installed the rear wheel and checked to see that it spins true, it‘s time to move on to the motor. Note: There are many ways to install your motor and people are coming up with new mounting ideas every day. We will be touching on a few different ones. Section 3: Installing Motor ![]()
STEP 17. Drill four ³“ holes for the U-bolts on the bottom part of the mount as shown. Note: If using the factory holes, it‘s best to drill the frame holes with your bike upside down. Follow steps 19 and 20 to mark where to drill the holes. ![]() ![]()
STEP 21. After adjusting the fit of the motor, mount the bolt into place using two U-bolts purchased at your local hardware store. Note: Don‘t forget the strips of rubber if you wish to protect the finish of your bike frame. Also, if you had to make adjustments to the mounting bracket you may want to touch up any scratches with black paint.

STEP 50. Cut the fuel line provided in the kit to the proper length. Then slide it onto both the ends of the petcock fuel valve and the inlet on the carburetor. Note: It‘s a good idea to get an inline filter for your fuel line. The petcock does have a screen filter, but small sediment can still get through.

10.Check local and state laws before riding your MOTOcycle on the street. 11.WARNING“ ALWAYS WEAR A HELMET WHILE RIDING!! OPERATING SUGGESTIONSEXHAUST SYSTEM:After 20 hours of operation, check the exhaust pipe for excessive oil and carbon buildup. Be sure to use the supplied support strap to secure the exhaust muffler to a solid anchor point on the bike frame or engine.
Note: Excessive periods of low-speed operation, idling, or leaving the fuel petcock in the —on“ position during shutdown periods may cause the pipe to become clogged with unburned fuel. CHAIN:Every time the bike is ridden, check the tension of the drive chain.
FASTENERS:Tighten all fasteners after every 5 hours of operation. 8 mm diameter cylinder head bolts and motor-mounting studs should be tightened to 9-10 ft./lb. using a torque wrench. Check before each and every ride. Use thread locker and lock washers on all connections. RIGHT-SIDE GEARS:Remove the cover plate and keep a small amount of heavy grease on the gear train. Do not over-grease, as leaks will occur and also may adversely affect the clutch operation. Regular greasing, if required, will help reduce gear wear and keep the gear train quiet. Check the gears weekly. Remove old debris and apply a small amount of grease to the inside of the gear teeth. BRAKE PADS:Fresh brake pads and clean rims assure proper braking. STARTING AND OPERATION INSTRUCTIONS
Note: I used non-synthetic oil during my first gallon mix at break-in to promote break-in wear. Then in the later mixtures, I used synthetic oil only for clean burn, low wear, and long engine life.

We offer these instructions to guide you through the installation. Please read through the instructions before beginning your installation. Happy motoring! Accessory Kit InstallationStep 1. Mounting the Headlight The headlight bracket included in your kit is mountable on the front fork. You can mount it above or below the wheel line. Be sure to give yourself room for the spokes. Shown here installed below the wheel line.
Step 2. If you prefer an alternative to the front fork placement, you can easily make your own bracket out of a steel or aluminum bar purchased from your local hardware store.
Step 6. Decide where on your bike you want the light installed. You can easily install the headlight on the handlebars by bending your newly fashioned bracket around the bar, and drilling another hole that lines up with the hole drilled in step five.
Step 7. If you prefer, you could bend the bracket into an —L“ shape and mount it to the front fork, above the wheel and behind the brake caliper. The light installs easily and does not affect the braking of the bike. Note: Most bicycle forks have a hole for a front brake caliper even if there is no brake caliper. ![]() ![]()
Step 12.Programming the Computer Press and hold the button on the front for 3 seconds; then let the button up. Choose between —kph“ or —mph“ by pressing the button. The display will change each time the button is pressed. When your choice shows on the display, press and hold the button for three seconds and release. Now you must calibrate the wheel. ![]() Wheel Calibration TableWheel Diameter in Inches: 16“ 18“ 20“ 22“ 24“ 26“ 28“ 28 x 1 ²“ Wheel Circumference: 128 144 160 176 192 208 224 228 Step 13. Now your display screen will show three zeros. Choose your wheel size from the calibration table above. The corresponding wheel circumference number directly below it is the number you will select. Begin pressing the button -the numbers will Increase in increments of one. After the tenth time the button is pressed, the numbers will begin to change rapidly.
Press the button to stop. Try to stop it just before the calibration number you are using. If you‘re setting it for a 26“ wheel, stop at 200 and move to 208 one number at a time. Once you have reached 208, press and hold the button for three seconds and the computer is set and calibrated. If you pass your target number, simply start over. Once setup is completed you can change between the functions by pressing the button once for each function. ![]() |
